Boost converter works with wide-range negative-input supply - 18-Mar-04
Issue of EDN Assume that a design requires positive voltage, but only a
negative-voltage power source is available. Using a standard boost-converter IC in the
circuit of Figure 1, you can efficiently generate a positive voltage from a negative
source. The boost converter generates an output voltage that's higher than the input
voltage.... [Design Idea by Mike Wong, Intersil Corp, Milpitas, CA] |

Buck boost regulator suits battery operation - 4-Sep-03 Issue of EDN A
buck/boost converter can step a voltage up or down. Such a converter is appropriate
for battery-powered applications. One application derives a regulated 14.1V at 1A from
12V solar panels with 9 to 18V variation. In this type of battery application,
efficiency is an important factor; hence, this design uses an inexpensive
synchronous-rectifier-based MC33166/7 circuit.... [Design Idea by Kahou Wong, On

Buck converter charger also provides system power - 05/22/97 EDN-Design
Ideas....Switching Regulator provides charge voltage setpoint with Current
regulation, and second Switching Regulator provides5V System Power -Many systems
require long-time operation during periods of power loss. Often, a gel or wet-cell
lead-acid battery is best choice because of high capacity and relatively low
cost. The battery charges.... [Design Idea by Robert Hanrahan, National Semiconductor,

Buck Mode Switching Regulator for Solar Applications - The purpose of a
voltage regulator circuit is to take a variable input voltage and produce a steady
output voltage. Two common regulator types are linear and switch-mode. Linear
regulators are simple, but waste a lot of power in the process of regulating the
voltage. Linear regulators can be thought of as self adjusting series resistors.
Switch-mode regulators such as this one are much more efficient. Switch-mode
regulators convert DC input voltages to pulses of high voltage DC. The DC pulses are
used to charge a storage capacitor to the desired output voltage. The voltage is
regulated by varying the width of the DC pulse.... [G. Forrest Cook] |
